Serviceberry or June Berry as some call it is most definately edible, I tried some off the tree this year before the birds got em all
anyway they didn't really have much flavor. If you look up service berry you will see that there are many different species but most of
them are very similiar. Heck You would have to be Hillbilly to tell em apart
I've found them here up to 6" in diameter but it seems
like the bigger they get the more twist they have and I for one can't see the twist as they have such a smooth bark. I cut about 20 last year and
I may have one or two that aren't to twisted to use.
